The 1860 election revealed how divided the country had become. There were actually two separate sectional campaigns: one in the North, pitting Lincoln against Douglas, and one in the South between Breckinridge and Bell. Only Stephen Douglas mounted a truly national campaign. The Republicans did not campaign in the South and Lincoln's name did not appear on the ballot in 10 states.
